Particles
Starting Point and Subjective Reason
The Japanese particle から serves two distinct functions for beginners. First, it attaches to nouns to mark the starting point of an action in time or space. Second, it attaches to the end of a clause to express a subjective reason or cause for the statement that follows.
01Main Functions
Marking a Starting Place
When attached directly to a place noun, から indicates where a movement or physical action originates.
アメリカから来ました。
(I) came from America.
Marking a Starting Time
When attached to a time word, から indicates the moment when an event, action, or state begins.
会議は３時からです。
The meeting is from 3 o'clock.
Expressing a Subjective Reason
When placed at the end of a sentence or clause, から explains the subjective reason for the statement that follows it.
忙しいですから、行きません。
Because (I) am busy, (I) will not go.
02Sentence Pattern
noun + から + verb + ました
アメリカから来ました。
(I) came from America.
When attached directly to a noun, から marks the starting point of a physical movement.
A は + noun + から + です
会議は３時からです。
The meeting is from 3 o'clock.
Attaching から to a time noun and finishing with です is a simple way to state when a scheduled event begins.
verb + ません + から + verb + ません
分かりませんから、行きません。
Because (I) do not understand, (I) will not go.
When stating a reason politely, から attaches directly to polite verb endings. The reason clause is placed before から.
verb (dictionary form) + から + verb + てください
帰るから、待ってください。
Because (I) am going home, please wait.
In plain speech, から follows the dictionary form of a verb. Using から is natural when the result is a direct request or command.
i-adjective + から + verb + てください
暑いから、休んでください。
Because (it) is hot, please rest.
から attaches directly to i-adjectives to explain the cause of a request, advice, or personal decision.
na-adjective + です + から + verb + ます
好きですから、買います。
Because (I) like (it), (I) will buy (it).
When stating a reason politely with a na-adjective, use the na-adjective without な and place です before から.
noun + だ + から + noun + です
日曜日だから、休みです。
Because (it) is Sunday, (it) is a day off.
Nouns require a linking word like だ or です before から to express a reason. Without the linking word, the sentence sounds like the starting point "from Sunday."

から attaches directly to the past tense form of i-adjectives, such as 寒かった.

When answering a どうして (why) question, から is placed at the very end of the sentence to show that the statement is a reason.
高くないから、買います。
Because (it) is not expensive, (I) will buy (it).
から can also attach to negative forms. Here it attaches directly to the negative i-adjective form ない.
04Comparisons
から vs. から～まで
While から alone marks the starting point ("from"), combining it with まで explicitly states both the start and end of a range ("from A to B"). This pattern is commonly used for both time and physical distance.
会議は３時からです。
The meeting is from 3 o'clock.
会議は３時から４時までです。
The meeting is from 3 o'clock until 4 o'clock.
から vs. ので
Both particles express a reason ("because"). However, から emphasizes the speaker's subjective logic or personal decision, making it natural before direct requests, commands, or opinions. ので sounds more objective, factual, and softer, making it preferred in polite explanations or formal apologies.
暑いから、窓を開けてください。
Because (it) is hot, please open the window.
05Nuance and Usage
The particle から serves as a fundamental marker for origin, easily translating to 'from' when attached to nouns. Whether it is a physical location like アメリカから (from America), a specific time like ３時から (from 3 o'clock), or a source like 友達から (from a friend), it clearly establishes where an action or state begins. In these contexts, it attaches directly to the noun without any extra linking words.
When used to express a reason, meaning 'because', から shifts from marking a physical origin to marking the logical origin of a thought. It is a subjective reason marker, highlighting the speaker's personal logic or motivation. This makes it the most natural choice when the following clause contains a command, request, suggestion, or expression of personal will, such as 暑いから休んでください (Because it is hot, please rest).
The formality of a から sentence is determined by the word that immediately precedes it. In casual Japanese, it attaches to dictionary-form verbs, plain i-adjectives, and nouns or na-adjectives followed by だ (e.g., 忙しいから, 休みだから). In polite speech, it attaches to polite verb endings and です (e.g., 忙しいですから, 休みですから). Remembering to include だ or です for nouns and na-adjectives is crucial for conveying a reason rather than just a starting point.
06Core Explanation
The Japanese particle から serves two distinct functions for beginners.
The Japanese particle から is a fundamental grammar tool that serves two distinct but essential purposes. For beginners, it is most commonly encountered as the marker for a starting point, acting as a rough counterpart to "from." However, when placed at the end of an entire clause, it acts as a conjunctive particle that expresses a subjective reason or cause, often translated as "because."
When used to indicate an origin, から attaches directly to nouns representing places, times, or sources. For example, in ３時から "from 3 o'clock" or 東京から "from Tokyo", the particle shows exactly where or when an action begins. This starting-point function behaves straightforwardly and directly follows the noun it modifies, setting the stage for the rest of the sentence.
The second major function of から is to explain why something happens. When used this way, から attaches to the end of the clause that contains the reason. Crucially, the Japanese sentence order places the reason first, followed by から, and then the result. A sentence structured as "reason clause + から, result clause" translates roughly to "Because (reason), (result)." Unlike the more objective particle ので, から emphasizes the speaker's subjective reasoning, making it the natural choice for justifying personal opinions, commands, and direct requests.
A common stumbling block for learners occurs when attaching the reason-marking から to nouns and na-adjectives. While verbs and i-adjectives can connect directly to から, such as 行くから or 寒いから, nouns and na-adjectives require a state-expression word like だ or です to bridge the gap. For instance, to state the reason "because (I) am a student", you must say 学生だから or 学生ですから. If you omit the linking word and simply say 学生から, the meaning reverts to the starting-point function, meaning "from a student."
Finally, から adapts easily to both casual and formal speech depending on the words that precede it. When speaking politely, you simply attach から to polite endings like ます or です, as in 忙しいですから: "because (I) am busy". In casual conversations among friends, plain dictionary forms are used, resulting in phrases like 忙しいから. Regardless of the formality, mastering から unlocks the ability to clearly explain the origin of actions and the logic behind your thoughts.
07Common Mistakes
Wrong
から忙しいです。
Correct
忙しいですから。
Why: In Japanese, the reason particle から must come after the reason clause, not before it like the English word "because".
Wrong
日曜日から、学校は休みです。
Correct
日曜日だから、学校は休みです。
Why: When stating a reason with a noun, you must use a copula like だ or です before から. "日曜日から" literally means "from Sunday."
Wrong
好きから、食べます。
Correct
好きだから、食べます。
Why: Japanese na-adjectives behave like nouns and require だ or です before から when stating a reason.
Wrong
暑いだから、泳ぎます。
Correct
暑いから、泳ぎます。
Why: Japanese i-adjectives connect directly to から. You cannot place だ after an i-adjective.
Wrong
行くだから、急ぎます。
Correct
行くから、急ぎます。
Why: Verbs connect directly to から in their dictionary form (or polite ます form). You cannot place だ after a verb.
Wrong
からいつですか。
Correct
いつからですか。
Why: Particles in Japanese attach to the end of the word they modify. To ask "from when", から must follow いつ.
08Questions
Can I start a sentence with から?
You cannot start a sentence with just から. However, you can start a sentence with だから or ですから, which means 'Therefore' or 'For that reason.' This connects your new sentence to the reason you just stated in the previous sentence.
How is から different from ので?
Both mean 'because', but から is subjective and focuses on the speaker's personal logic, making it great for commands and opinions. ので is more objective and factual, which sounds softer and is often used in polite apologies or formal explanations.
Why do I sometimes see から used with まで?
から (from) and まで (until/to) are often paired together to show the start and end of a physical distance or a period of time, such as 月曜日から金曜日まで (from Monday to Friday).
